How do you determine how many dots to put around the Lewis symbol of an element?
Step 1 of 5 In Lewis’ structures, we need to represent only the electrons of the valence shell. Every electron can be represented as a dot. Step 2 of 5 We need to know the electronic configuration of the element we are interested in Step 3 of 5 Example For Sulphur, we know that the electronic configuration is 1s , 2s , 2p ,3s , 3p . 2 4
